Description

Vorrichtung zur Gebäudebelüftung  Device for building ventilation
Die vorliegende Erfindung betrifft eine Vorrichtung zur Gebäudebelüftung mit Wärmerückgewinnung. Insbesondere betrifft die vorliegende Erfindung eine derartige Vorrichtung zur Gebäudebelüftung mit der die Wärme der Raumluft, die nach Außen geführt wird, zurückgewonnen und mit der zurückgewonnenen Wärme kalte Außenluft, die nach Innen geführt werden soll, vorerwärmt werden kann. Eine regelmäßige Raumbelüftung ist unerlässlich, da eine schlechte Belüftung gravierende Folgen haben kann. Eine ungenügende Belüftung führt nicht nur zu einem schlechten Wohnklima, sondern verhindert auch einen Ausgleich des Feu chtig keitsgeh a lts d er Ra u m l uft, d er zu ei n em M uffgeruch u n d i m schlimmsten Fall zur Schimmelbildung führen kann. The present invention relates to a device for building ventilation with heat recovery. In particular, the present invention relates to such a device for building ventilation with the heat of the indoor air, which is led to the outside, recovered and with the recovered heat cold outside air to be led to the inside, can be preheated. Regular room ventilation is essential, as poor ventilation can have serious consequences. Inadequate ventilation not only leads to a poor indoor climate, but also compensates for the lack of moisture in the room, which can lead to a bad smell and, in the worst case, mildew.
Andererseits führt gute Belüftung insbesondere in der kalten Jahreszeit zu einem erheblichen Wärme- und damit Energieverlust. On the other hand, good ventilation, especially in the cold season, leads to a considerable loss of heat and energy.
Einerseits wird warme Raumluft nach Außen geleitet und andererseits muss kalte Außenluft auf die gewünschte Raumwärme erwärmt werden. Die Belüftung von Räumen oder Gebäuden erfolgt üblicherweise durch aktives Belüften, wobei Fenster oder Türen angekippt oder geöffnet werden. Diese Art der Belüftung erhöht jedoch das Einbruchsrisiko.  On the one hand warm room air is led to the outside and on the other hand cold outside air has to be heated to the desired room heat. The ventilation of rooms or buildings is usually carried out by active ventilation, with windows or doors are tipped or opened. However, this type of ventilation increases the burglary risk.
Bekannt sind lüftungs- und klimatechnische Anlagen , die bei Gebäuden eingesetzt werden, und die als Wärmerückgewinnungssystem ausgeführt sind, wobei die Wärme der verbrauchten Abluft über ein Wärmetauschersystem entzogen wird und bei Bedarf auf die zu erwärmende Außenluft übertragen wird. Diese Wärmerückgewinnungssysteme können als Kreislaufverbundsysteme ausgeführt sein, wobei sich ein Wärmeaustauscher in der Abluft zur Aufnahme der Wärme aus der verbrauchten Abluft und ein Wärmeaustauscher in der Außenluft, zur Abgabe der aus der Abluft zurückgewonnenen Wärme befindet. Eine Weiterbildung dieser bekannten lüftungs- und klimatechnischen Anlagen ist Gegenstand von DE 10 2005 008 565 A1 die zusätzlich zur Wärmerückgewinnung eine Nachkältegewinnung und insbesondere Nachkältekühlung ermöglicht. Are known ventilation and air conditioning systems that are used in buildings, and are designed as a heat recovery system, the heat of the exhaust air is removed through a heat exchanger system and is transmitted to the outside air to be heated if necessary. These heat recovery systems can be designed as closed loop systems, wherein a heat exchanger in the exhaust air to absorb the heat from the spent exhaust air and a heat exchanger in the outside air, for the discharge of the heat recovered from the exhaust air. A development of these known ventilation and air conditioning systems is the subject of DE 10 2005 008 565 A1 which in addition to Heat recovery enables aftercooling and especially postcooling cooling.
Diese bekannten Anlagen sind üblicherweise in einer Aussparung des Mauerwerks eingesetzt oder als Vorschalt- beziehungsweise Anbaugeräte ausgebildet und mit dem Gebäudeinneren verbunden.  These known systems are usually used in a recess of the masonry or formed as Vorschalt- or attachments and connected to the building interior.
Erfindungsgemäß wird ein Belüftungssystem vorgeschlagen, dass eine effiziente Belüftung von Räumen oder Gebäuden ermöglicht, ohne dass Fenster oder Türen gekippt oder geöffnet werden müssen. According to the invention, a ventilation system is proposed that allows efficient ventilation of rooms or buildings without having to tilt or open windows or doors.
Ferner ermöglicht das erfindungsgemäße Belüftungssystem eine Rückgewinnung der Wärme der Raumluft, die nach Außen geführt wird, wobei die rückgewonnene Wärme gleichzeitig zur Vorerwärmung der kalten Außenluft eingesetzt werden kann, die von Außen in den Raum oder das Gebäude eingeleitet wird. Further, the ventilation system according to the invention allows a recovery of the heat of the room air, which is led to the outside, wherein the recovered heat can be used simultaneously for preheating the cold outside air, which is introduced from the outside into the room or the building.

Zumindest in den Bereichen, in denen die Luft zwischen den inneren und äu ßeren E nt- beziehungsweise Belüftungsöffnungen strömt, sol lte das Gebäudeelement einen ausreichenden Hohlraum aufweisen, um den Luftstrom zu gewährleisten. Hierzu können die Wärmetauscher auch wendeiförmig gestaltet sein, so dass der Luftstrom innerhalb der Wendel erfolgen kann. At least in the areas where the air flows between the inner and outer openings or vents, the building element should have sufficient cavity to ensure airflow. For this purpose, the heat exchanger can also be designed helical, so that the air flow can take place within the helix.
Die Belüftungs- beziehungsweise Entlüftungsöffnungen können eine beliebige geeignete Form aufweisen . Sie können auch aus einem luftdurchlässigen Material gebildet werden. Beispiele für geeignete Formen sind runde oder eckige Öffnungen, schlitzförmige Öffnungen etc. Die Anzahl der inneren und äußeren Entlüftungsöffnungen 4, 5 beziehungsweise der inneren oder äußeren Belüftungsöffnungen 6, 7 kann je nach Bedarf gewählt werden. The vent openings may have any suitable shape. They can also be made of an air-permeable material. Examples of suitable shapes are round or square openings, slot-shaped openings, etc. The number of inner and outer ventilation openings 4, 5 or the inner or outer ventilation openings 6, 7 can be selected as needed.
Sie kann sich an der Länge des Wärmeaustauschers im ersten beziehungsweise zweiten Bereich orientieren.  It can be oriented along the length of the heat exchanger in the first or second region.
Vorzugsweise wird die Anzahl so gewählt, dass der Bereich mit den inneren Öffnungen nicht mit dem Bereich mit den äußeren Öffnungen überlappt.  Preferably, the number is selected so that the area with the inner openings does not overlap with the area with the outer openings.
In dem oberen Randteil sind innere Entlüftungsöffnungen 4 angeordnet, durch die die Raumluft aus dem Raum heraus in das Innere des Randes geleitet wird. Weiter sind äußere Entlüftungsöffnungen 5 vorgesehen, durch die die Raumluft aus dem Randinnern in die Umgebung ausgeleitet wird. In the upper edge part inner ventilation openings 4 are arranged, through which the room air is led out of the room into the interior of the edge.

Wie im ersten Bereich 2 sind die inneren Belüftungsöffnungen 6 und äußeren Belüftungsöffnungen 7 entlang des Wärmeaustauscherelements angeordnet, wobei sich die äußeren Belüftungsöffnungen 7 stromaufwärts zu den inneren Belüftungsöffnungen 6 befinden.  As in the first area 2, the inner ventilation openings 6 and outer ventilation openings 7 are arranged along the heat exchanger element, the outer ventilation openings 7 being located upstream of the inner ventilation openings 6.
Kalte Außenluft dringt durch die äußeren Belüftungsöffnungen 7 in das Randinnere ein und strömt entgegen der Fließrichtung des Wärmeaustauscher- mediums zu den inneren Belüftungsöffnungen 6, wo die erwärmte Außenluft aus dem Rand in den Raum hineinströmt. Cold outside air penetrates through the outer ventilation openings 7 into the edge interior and flows counter to the flow direction of the heat exchanger. medium to the inner ventilation openings 6, where the heated outside air flows from the edge into the room.
Durch die Anordnung der Entlüftungsöffnungen 4, 5 im oberen Randteil und der Belüftungsöffnungen 6 , 7 i m u nteren Randteil macht sich die vorliegende Erfindung zur Nutze, dass warme Luft nach oben strömt, sodass in einem gesch l ossen e n Ra u m ü bl i ch erwei se d i e L uft i m Be rei ch d er Decke , beziehungsweise der Oberkante des Fensters eine höhere Temperatur aufweist als im unteren Bereich des Fensters oder Raumes. Diese Temperaturdifferenz wird bei dieser Anordnung ausgenutzt. As a result of the arrangement of the vent openings 4, 5 in the upper edge part and the ventilation openings 6, 7 in the lower edge part, the present invention makes use of the fact that warm air flows upwards, so that a flow is avoided in a closed loop The temperature in the ceiling or upper edge of the window is higher than in the lower area of the window or room. This temperature difference is utilized in this arrangement.
Zumindest die äußeren Ent- und Belüftungsöffnungen können nach außen mit einem Sieb versehen sein, um zum Beispiel das Eindringen von Insekten zu verhindern und das gegebenenfalls als Schallschutz wirken kann. At least the outer venting and venting apertures may be outwardly provided with a sieve to prevent, for example, insect intrusion and which may optionally act as soundproofing.
Der Umlauf des Wärmeübertragungsmediums kan n du rch die natü rl iche Konvektion, beziehungsweise Wärmeausdehnung, bewirkt werden. The circulation of the heat transfer medium can be effected by means of the natural convection or thermal expansion.
Bei Bedarf oder unterstützend können zum Beispiel elektrische Pumpelemente vorgesehen werden. Der Betrieb der elektrischen Pumpelemente kann über einen Stromanschluss erfolgen. If required or supportive, for example, electrical pumping elements can be provided. The operation of the electrical pumping elements can be done via a power connection.
Gemä ß ei n er bevorzugten Au sfü h ru n gsform kön n en d ie el ektrisch en Pumpelemente über Solarzellen betrieben werden, die Außen am Gebäude, zum Beispiel auch am Fensterrahmen oder im Bereich des Fensterrahmens, montiert sein können. Gemäß einer weiteren Ausführungsform kann der Antrieb der Pumpelemente auch durch den Luftstrom im System erfolgen.  According to a preferred embodiment, the elec trical pumping elements can be operated via solar cells, which can be mounted on the outside of the building, for example also on the window frame or in the area of the window frame. According to a further embodiment, the drive of the pumping elements can also be effected by the air flow in the system.
Gemäß einer Ausführungsform können ein oder mehrere Rückschlagventile 8, 9 vorgesehen sein. Die Rückschlagventile 8, 9 unterstützen die Fließbewegung des Wärmeübertragungsmediums, die sich aufgrund der mit der Erwärmung und Abkühlung des Wärmeübertragungsmediums verbundenen Druckdifferenz ergibt. According to one embodiment, one or more check valves 8, 9 may be provided. The check valves 8, 9 support the flow of the heat transfer medium resulting from the pressure difference associated with the heating and cooling of the heat transfer medium.
In der in der Figur gezeigten Ausführungsform ist ein unteres Rückschlagventil 8 in dem Wärmeaustauscherelement 1 unmittelbar vor Eintritt der Wärme- Übertragungsflüssigkeit in den unteren Bereich 3 sowie ein oberes Rückschlagventil 9 unmittelbar vor Eintritt der Wärmeübertragungsflüssigkeit in den oberen Bereich 2 vorgesehen. Vorzugsweise ist das Wärmeaustauscherelement 1 zumindest in dem Bereich, der zwischen den inneren Entlüftungsöffnungen 4 und den inneren Belüftungsöffnungen 6 liegt, wärmeisoliert, um eine vorzeitige Abkühlung des erwärmten Wärmeübertragungsmediums zu verhindern. In the embodiment shown in the figure, a lower check valve 8 is provided in the heat exchanger element 1 immediately before the entry of the heat Transfer liquid in the lower region 3 and an upper check valve 9 is provided immediately before the entry of the heat transfer fluid in the upper region 2. Preferably, the heat exchanger element 1 is thermally insulated at least in the area between the inner vents 4 and the inner vents 6 to prevent premature cooling of the heated heat transfer medium.
Auch der Bereich des Wärmeaustauscherelements 1 zwischen äußeren Belüftungsöffnungen 7 und äußeren Entlüftungsöffnungen 5 kann Wärme isoliert sein.  Also, the area of the heat exchanger element 1 between outer vents 7 and outer vents 5 may be heat insulated.
Der Wärmeaustauscherkreis kann zur Unterstützung der Erwärmung mit einem oder mehreren Sonnenkollektoren verbunden sein. The heat exchange circuit may be connected to one or more solar panels to assist in heating.
Als Wärmeübertragungsmedium kann ein beliebiges bekanntes fluides Wärmeübertragungsmedium eingesetzt werden. Beispiele hierfür sind wasserbasierte Substanzen, olbasierte Substanzen oder Kühlmittel, wie sie aus der Klimatechnik bekannt sind. As the heat transfer medium, any known fluid heat transfer medium can be used. Examples include water-based substances, oil-based substances or coolants, as they are known in the air conditioning industry.
Die Form des ersten und zweiten Wärmeaustauschers unterliegt keiner speziellen Beschränkung. Sie sollte jedoch eine ausreichende Oberfläche aufweisen, um eine effiziente Wärmeübertragung zu gewährleisten. The shape of the first and second heat exchangers is not particularly limited. However, it should have sufficient surface area to ensure efficient heat transfer.
Der Wärmeaustauscher kann zum Beispiel schlangenlinienförmig verlaufen, oder als Wendel ausgebildet sein. The heat exchanger may for example run serpentine, or be formed as a helix.
Er kann oberflächenvergrößernde Elemente aufweisen, wie Lamellen oder Stifte, die aus einem Material gefertigt sein sollten, das eine gute Wärmeleitfähigkeit aufweist, zum Beispiel einem Metall oder Metalllegierung. Bezugszeichenliste It may have surface enlarging elements, such as fins or pins, which should be made of a material having good thermal conductivity, for example a metal or metal alloy.
